Instance Crashes

Is all the data deleted when an instance crashes? Or are we able to recover the losses? Being rolled back and losing all inventory and interactions done that map makes the game unplayable.

I don't mind being disconnected from the server as long as I can go back in the map and I don't lose my whole inventory.

when the servers chrash ( which happens all the time atm on EU Server) there is a rollback of a few mins whenever the last save was serverside!
